WASHING-MACHINE.

Specicaton of Letters'Patent.

Patented April 16, i907.

Application led January 21, 1907. Serial No. 353,373.

To @ZZ whom, t may concern:

Beit known that I, JAMES SCOTT PARRisH, a citizen of the United Statesof America, and a resident of Richmond', in the county of Henrico andState of Virginia, have invented certain new and useful Improvements inWashing-Machines, of which the following is a full and clearspecification, reference being had to the accompanying drawings, inwhich- Figure 'l is a side elevation of an oscillatingtubwashing-machine provided with my improvement. Fig. 2 is a verticalsectional view through the upper part of the cover of tub, showing themanner of connecting the rubber stem or shaft to the cover.

This invention has reference particularly to the oscillating-tub type ofwashing-machine, in which the tub is rotatably mounted on a verticalpivot attached to its bottom, and the rubber disk inside the tub is heldagainst rotation by means of a stem attached thereto and passing upthrough the cover of .the tub and locked against rotation by means of arod or bar connected at a convenient point to a stationary part of theframe, the rubber disk or dolly being gravitatingly supported so that itrests upon the body of clothing being washed.

The object of the present improvement is to provide simple means wherebythe flat horizontal rubbing disk or dolly shall be automatically andpositively moved up and down during the oscillation of the tub back andforth, the tub itself'causing this intermittent vertical reciprocationof the disk and its shaft, as more fully hereinafter set forth.

To the accomplishment of this object and such others as may hereinafterappear the invention consists of the parts and combination of partshereinafter fully described, and

particularly pointed out in the appended claims, reference being hadto'the accompanying drawings, forming a part of this speciiication, inwhich the same reference characters designate like parts throughout theseveral views.

Referring to the drawings by reference characters, A designates the tub,which is rotatably mounted in the usual way and is adapted to beautomatically returned at the end of each of its oscillations inopposite directions by means of the usual springs mounted on thetub-support below the tub.

The letter B designates the usual horizontal rubber mounted in the tuband provided with a shaft or stem O, which is rectangular incross-section and passes up through the hole in the cover of the tub andis provided at its upper end with a handle c formonvenience in liftingit when the cover is to be swung open. This. angular rod or stem is heldagainst rotation by means of a horizontal rod D, which at one end isdetachably connected in a suitable way to a stationary part of the benchand at its other end is provided with a squared head d, through whichthe squared rod'loosely passes and by which it is held against rotation.

Affixed to the shaft O of the rubber is a collar E, which may beadjusted up and down and rigidly aflixed in its adjusted position bymeans of a set-screw e, this vertical adustment being for .the purposeof enabling the machine to be adapted for batches of clothing ofdifferent sizes. Projecting from diametrically opposite points of thiscollar are a pair of pins e', each of which carries anantifriction-roller. These rollers engage in an internal cam-grooveformed in a cast ring F, affixed to the top of the tub-cover.

It will be observed that as the tub is oscillated back and forth the camplate or ringand releasing action in addition to the rotary rubbingaction, whereby the cleansing of the clothing will be greatlyfacilitated without adding materially to the power required to oscillatethe tub.

A great desideratum in this class of machines is that the tub shall berotatable with the least possible expenditure of energy. With myattachment I accomplish the desirableintermittent squeezing of theclothing without adding materially to the friction of rotation,since Iavoid bodily raising and lowering the tub to cause the rotation of thetub to ltransmit to the rubbing-disk the vertical movement desired.

My attachment also enables me to quickly adjust the machine fordifferent batches of clothing, since this adjustment is accomplishedsimply by loosening the set-screw e and then raising or lowering therubber to the desired point and then securing it at that point.

Having thus fully described my invention,

IOO

what I claim, and desire to secure by Letters Patent, is-

1. In combination with a support, a horizontally-rotatable tub mountedthereon, la

rubbing-disk within the tub and provided with a shaft extending upthrough the cover thereof, means engaging the upper end of this shaft tohold it against rotation, a vertically-adjustable collar on this shaftcarrying radial pins, and a cam device secured to the top of the tub andengaging said pins, for the purpose set forth.

2. The combination of a support, an oscillating tub having a cover, arubber in the tub carrying a shaft extending up out through the cover,means engaging this shaft for holding it against rotation, and means forraising and lowering said shaft during the oscillation of the tub, saidmeans consisting of two members one a cam and the other a radial device,one member being on the shaft and holding it against rotation, and meansforA raising and lowering said shaft during the oscillation of the tub,said means consisting of a cylinder affixed to the top of the tub andcarrying an internal cam, and a radial device attached to said shaft andengaging in said cam, for the purpose set forth.

In testimony whereof I hereunto affix my signature, in the presence oftwo witnesses, this 19th day of January, 1907.

JAMES SCOTT PARRISH.
